Adding Web ControlDear All
I am writing a tool which requires to have controls added to it dynamically. To make the task more complex, the addition of the control cannot happen anywhere but it has to be instead of a token example <p> this is a test <textbox /> and a text box should be entered </P> the tool should render the message and instead of <textbox /> it should show an ASP.Net textbox control Please note that position cannot be predetermined Thanks for the support, it will be appreciated Duncan Are you allowed to parse and then display? If so, you can set up the page
with a pass and then redirect the user to the new page If this is not a possibility, you will have to set up a handler to create the parse and display bits. The easiest might be inheriting from the page class and creating the scripting engine to display from a raw parse. Either way, it is going to be a pain. -- Show quoteHide quoteGregory A.

Use regular expressions
or string.replace to replace the keyword tokens with valid asp.net syntax. Then, call the ParseControl() function to render the output. This will return a new control with all the child elements instantiated and you can add it to the current page. If you plan on manipulating or using the new controls on subsequent postbacks you'll need to add the parsed control in the init event for them to work properly.

I have managed to add controls to a page and handle the event of the button which solves the first part of the problem - second is then quite easy as one will just need to find the token and split the text in two variables or array Code for initial part is shared below in case you are having the same problem like me Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init Dim c As Control 'declare control c = ParseControl("HelloWorld <br /> ") 'parsecontrol takes text as well as html form1.Controls.Add(c) 'add control to form c = ParseControl("<asp:Button ID=""Button1"" runat=""server"" Text=""Button"" />") 'html for button form1.Controls.Add(c) Dim btn As Button = FindControl("Button1") AddHandler btn.Click, AddressOf MyOtherClick 'add event handler for button c = ParseControl("<asp:TextBox ID=""Searchbox"" runat=""server""></asp:TextBox>") form1.Controls.Add(c) 'adding a textbox control c = ParseControl("<br /> End Here") form1.Controls.Add(c) 'adding html End Sub Private Sub MyOtherClick(ByVal sender As Object, ByVal e As EventArgs) Dim tb As TextBox = Me.Page.FindControl("Searchbox") MsgBox(tb.Text) 'display contents of text box End Sub Duncan Show quoteHide quote "Michael Hamrah" <mham***@gmail.com> wrote in message news:1161100262.570917.186700@m7g2000cwm.googlegroups.com... > On postback, pull the string from the textbox.
